Hi All

I have a diagram , that has the scales , I can read it but to use the data, I was searching for a better method , for example if I scan it, since it is in PDF format, how can I read all the points of the Diagram and export it to Excel ?

Please tell me all the steps

Thank you very much

Best Regards
